Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This Cloud model promotes availability and is composed of five essential characteristics, three delivery models, and four deployment models.

Five Essential NIST Cloud Characteristics

On-demand self-service

Ubiquitous network access

Location independent resource pooling

Rapid elasticity

Measured service.

Note Cloud software takes full advantage of the Cloud paradigm by being service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability.

First round winners

Hardware vendors best global demand since 1990s

Later rounds

Fewer buyers with high hardware demand can dictate technology and margins

Commoditization of software and operating systems, shift to open source

Software Business Model tying to of users of cores will be difficult, no up-front fees, no maintenance fees

By 2012 Intel predicts that some 20 to 25 percent of its server chips will be dedicated toward data centers that power Cloud Computing.

The federal government currently spends almost half of its 70 billion IT budget on infrastructure, costs that could be significantly reduced by shifting to software and infrastructure as a service.

Clouds are here to stay many research organizations will transition to private/public Cloud infrastructures for elasticity and cost-efficiency in their data analysis work.

The Office of Management and Budget will unveil its storefront for Cloud Computing services in early September. Industry and government sources say federal chief information officer Vivek Kundra is eyeing Sept. 9 at the Gov 2.0 Summit in Washington as the public launch of one-stop shop for Cloud Computing services.

An architecture (best practices for implementing and using technology resources)

A shortcut to avoid creating an architecture

A fix for architecture

A fix for security

Open and interoperable (at the moment)

Technical

Porting legacy applications and databases is NOT trivial

Multi-tenancy

Metadata driven business logic

SOA

Policy

Need to develop and baseline performance metrics and establish monitoring

Pay-as-you-go fees

Network perimeter defense no longer applies

Cloud Computing introduces a new set of security challenges

Security strategy must account for all layers and tiers of the Cloud environment

In January, 2009, a non-production stand-alone prototype portal overlaid onto a commercial Cloud provider, demonstrating that execution on a commercial Cloud environment without changes to the code base was possible

Initial performance testing of the unmodified and un-tuned system with the minimum configuration of 8 CPUs achieved 2,600 concurrent users with 90 data element application registrations at a cost of 2.42 including software

18How Should I Use the Cloud Today?

Surge

Utilized when the IT infrastructure is not adequate to support an increase in demand or volumes

Removes the need to acquire IT infrastructure that sits idle or is under utilized

Public Information

Static information that is accessible by the public, visible today but housed within the IT boundaries of the enterprise

Test and Development Environments

Development Environments

Project Specific, Limited time use, Version control, Non production data
